How the System Works--This vehicle reversing aid has two 6-stage audible warning signals that change according to the distance to the obstacle detected by the system's miniature rear-bumper-mounted sensors. The VDI (Voice Distance Indicator) "tells" the driver un a clear voice the following distances: "8 Feet. 5 Feet, 3 Feet, 2 Feet, 12 Inches and Crash." Integrated with the VDI is a beeping system that increases in pulse frequency as the vehicle distance decreases. With 2 audible signals to warn you, you can back up your vehicle with complete confidence.

Check what typical "minor" backing-up accidents cost to repair and you will see that the Back-up Sensor can easily pay for itself many times over by preventing just one accident. Read the full specifications and see who is using it.

Look what just $223 gives you!


  • 8-bit microprocessor with built-in VDI technology makes our system accurate and reliable day or night.
  • Voice range read out up to 8 feet. Synchronizes with the motion of your vehicle.
  • Distinctive audio warning system. Increases in pulse frequency as your vehicle gets closer to the obstacle.
  • Prominent warning signals. "Crash" means object is less than 8 inches from vehicle. "Object in Blind Area" warns that an object has fallen into a non-detecting zone--caution advised.
  • 1-year limited manufacturer's warranty.


  • Peace of Mind--

    Our system can detect an object as narrow as a 4" pole

  • Minimize Accidents--

    Protect your passengers and your company. Avoid injuries while backing up.

  • Save money--

    The cost of this backup alert system is often less than the insurance deductible for an accident. Look at who's using it.
